Is a DVD ISO file equivalent to a DVD?
Posted on 2004-10-11
I plan to back up dozens of DVDs to an external hard drive connected to my laptop by using DVD Decrypter 18.104.22.168 to create ISO images. Before I buy the external 200 GB hard drive, I want to make sure my idea is going to work. I've tested DVD Decrypter on my computer by saving several DVDs as ISOs to my local hard drive and I can play them back fine (using Virtual DAEMON Manager V3.47 to make the ISO a virtual DVD drive and then playing it with a standard DVD software player).
I'm pretty sure I'll be able to burn the ISOs to the external hard drive and watch the DVDs on my laptop. However, to plan for the future I also want to be sure that later I'll be able to do whatever I want with this ISOs. In particular, I want to know if in a few years I should be able to burn them to DL DVDs that will play in most/all standard DVD players (once the price of DL DVDs comes down), use programs such as DVD Shrink to put them on CD-Rs, put them on a MythTV box, or basically do anything I could do if I had the original DVD. In other words, is the ISO created by DVD Decrypter equivalent to having the DVD itself? I assume that my computer can't even tell the difference between the ISO and the DVD (if I use the Virtual DAEMON Manager).
Please don't respond with "Yeah, that should work." I already know it probably should work. I want to know that it WILL work. I know some of you are real experts, so if you say it will, I'll believe you, but I'd also appreciate any links you can provide as a reference.
The only barriers I see are that somehow the decoding to an ISO changes it in a way that I can't get it back onto a DL DVD in a way that will play on most players, or that there is a strong expectations that software to do this will no longer be available in a few years for legal reasons. Any recommendations on particular settings I need to use for DVD Decrypter to make sure this is going to work? (I'm currently using settings such as "Remove Macrovision Protection" and removing all other types of protections (IFO/BUP).) I really really don't want to spend months saving all these DVDs as ISOs only to find out later that I can't use the ISOs because I somehow saved them wrong due to the fact that I didn't remove a protection (or removed one that I shouldn't have).
Thanks in advance!
